Simon Cowell fights tears during Nightbirde's emotional return.
"America's Got Talent" contestants laid it all on the line Tuesday to advance to the semifinals, but one Golden Buzzer winner didn't have the chance to.
"It was a great show (last night) but there was somebody missing –  Nightbirde," Terry Crews said during Wednesday's live results show, referring to Ohio singer Jane Marczewski, who previously shared she has a "2% chance of survival" with "some cancer in my lungs, spine and liver."

Marczewski – who earned Simon Cowell's Golden Buzzer following an emotional performance about being more than her cancer –  revealed on Instagram  earlier this month she was withdrawing from the competition because her "health (took) a turn for the worse."

The singer virtually returned Wednesday to provide an update following her departure.
"I cannot say thank you enough for the opportunity to have a moment to share my story and we are witnessing such a beautiful picture of the human spirit," she said, adding that the overwhelming amount of support she received has "restored my faith in humanity."

Cowell said Marczewski made the right decision to focus on "your wellbeing, your health and your recovery."

"You made the decision, rightly so, that your health is your priority right now and I know the last time we spoke you actually said that you feel like you let people down," Cowell told her, holding back tears.
